The first improvements to St Denys Road (A3035) and A335 Thomas Lewis Way (A335) were completed in late 2022.
These junction improvements included:
- New intelligent traffic signals at the junction providing smoother and more efficient traffic movements in the area
- A new cycleway along St Denys Road, crossing the junction, and safer crossing points for pedestrians
The works were completed in phases that will require lane restrictions and some overnight closures, with the final phase (Phase 4) currently being undertaken throughout June and July 2023.
Phase 1
The traffic management was put out on the evening of Sunday 21 August for our works to start on Monday 22 August. To create a safe working area for our team we removed all eastbound access from Portswood onto the junction, however all westbound traffic from Thomas Lewis Way and St Denys was able to pass through.
We also removed the dedicated left hand turning lane from St Denys onto Thomas Lewis Way. Traffic, excluding HGVs, was able to turn left (southbound) using the other lanes. Due to the tight turning circle here, HGV’s needed to follow the signed diversion route.
Our work required us to upgrade the ducting that runs under the road surface, therefore, to minimise disruption to traffic, we worked overnight during the first week, from Monday 22 August for 5 nights, to undertake this element of the work.
Phase 2 and 3
During this second phase we worked on the western approach from Portswood, this area continued to be one way throughout this phase. There was a change of traffic management in the area to place vehicles on the opposite carriageway, however the access restrictions remained the same throughout. Pedestrian access was maintained.
Once completed we then progressed to the third phase which saw our teams working more in the pedestrian areas of the junction, on the eastern side of St Denys Road near to Osborne Road North. These included the addition of tactile paving to assist with pedestrians crossing the road. At the same time, we installed a crossing point on the island opposite on the western arm of the road.
Once these phases of work were complete, the final part of these works included resurfacing and relining the road to make it ready for reopening.
